Application filed January 3, 1928, Serial 110 244330. Renewed January28, 1930.

This invention relates to machines for operating on the toe portions ofstitchdown shoes, and particularly to machines for lasting the toeportions of such shoes and for.

pressing their outturned flanges.

In one system extensively used in making stitchdown shoes, an extensionsole is fastened to the bottom of a last and a lining and an upper areassembled upon the last. A heated toe box of absorbent materialcontaining wax and gum is placed between the upper and lining at thetoe, and the upper, including the toe box, is shaped over the last, themargins of the upper, boxland lining being outtu'rnedand pressed againstthe projecting margin of the sole. The pressure exerted causes some ofthe melted gum to be forced through the lining which is thus caused toadhere to the margin of the sole. Thepressure exerted on the upperduring the lasting operation also forces some of the melted wax and gumout of the toe box against the inner surface of theupper and theoutersurface of the lining, so that when the wax and gum cool the upperand lining adhereto the toe box and the adhesion of the flanged marginof the lining to the sole holds all the upper-materials 1n lasterposition; Objects of this invention are generally to improve and perrectmachines for lasting stitchdown shoes and to provide I a convenient,effective and speedy machine for this work without sacrificing any ofthe advantages of prior machines. 7

In the organization of the illustrated machine, a pair of wipers isprovided, the wipers being" constructed and arranged for advancing andclosing movement relatively to the shoe but having no movementheightwise of the shoe. The Wipers are preferably arranged in ahorizontal planein fullview of the operator and withithe opening betweenthem facing the operator. The shoe is-pretented right side up to thewipers' and in-a plane below the wipers, the bottom of'the gshoe restingon a support having a sole-sup porting face parallel to the plane ofthe" wipers and of sufficient extent to support the last and the shoe,"including the projecting margin of the sole attached to tl 'elastx Thesupport is arranged formovement heightwise and the sole. organized tostop with the'work under pres- "sure togive time for the uppermateriallsto of the shoe to effect wiping action of the v wipers at theend and sides of the last toward the last bottom. In the illustratedmachine, the wipers are operated to advance and close upon theshoeinconjunction with the height- 3.

wise movement of the'support, the wipers being thereby positioned inwiping relat on to the "shoe during said heightwise movement.

.Also, asillustrated,the heightwise movement of the shoe supportrelatively to the wipers is preferably in a path inclined toward thewipers so that, as theshoe'ismoved upwardly through the wipers,it willbe also crowded lengthwise toward the wipers. Also, as illustrated, theshoe support is constructed and arranged for tipping movement about anaxis turned flange of the upper and the projecting margin of the sole atthe'two sides of the shoe in case the upper materials'or the sole Shouldbe of different thickness at the two sides of the shoe. As illustrated,the shoe support is moved by manually operated means Whichis alsoconnected to the Wipers to efiect their-operationin conjunction with themovement of the support; The manually operated means is adapted forrepeated operation to workthe upper into lasted position and, after thewiping operation has been satisfactorily effected, is, in theillustrated machine, constructed and arranged tohave a further movementby which power-operated means is set in opera tion to effect relativemovement between "the shoe support and Wipers and to press the outturnedflange of'the upper and the projecting margin of the sole'fii'mlytogether and, if the upper materials include cement, to causefirm adhesion between the upper materials Pre'ferably'the power means isset in lasted condition and for the adhesionto take place.

In the illustratedmachine, the connections between the work support andthe wipers for ef'fecting their advancing and closing movements includeyielding means, shown as a spring, by which the wipers are maintained inyielding engagement with the upper during the heightwise movement of theshoe between them, andthe connections between the manually operatedmeans and the shoe sup port also include yielding means, perferably a; srin Thetwo ieldin means permit.

P e y g movement of the manually operated means after the movement ofthe shoe support has been arrested by contact of the projecting marginof the shoe with the wipers: to permit the power means to be set inoperation. Moreover, in the illustrated machine, as the wiping operationis caused to progress by upward novement of the shoe support the tensionof the Wiper operating spring is progressively increased, so that at thefinal portion of the lasting operation when the upper is beingworkedinto the angle between the side ofthe last and theprojecting margin ofthe sole, the wipers are held firmly advanced and closed to'shape theupper into said angle.

' These and other novel constructions and combinations of parts will beunderstood from the following detailed description when jread inconnection with the accompanying drawings and will be pointed out in theappended claims. r In the drawings, I Fig. 1 is a side elevation of astitchdown lasting machine embodying the present invention; i

. Fig.2 is a1detailed view of the shoe sup- ..port and wipers showingthe shoe in section and the wipers locatedat the termination of the,lasting operation; 7 V Fig. 3 is a plan view of the head of themachineyand Fig. 4 is a front elevation of ,the parts .shown in Fig. 3.j

; The illustrated machine is designed for lasting the toe portions ofstitchdown shoes N by shaping the upper of the toe portion to D the lastand pressing the outturned margin of the upper against the projectingmargin of the sole. 7

Referring now to Fig. 1 of the drawings, the numeral 10 indicates aframe on the upper portion 12 of which is mounted a wiper headconsisting of a block 14 having a flat upper .surface' arranged in ahorizontal plane and a cover plate 16 between which'are disposed apairof wiper carriers 18, 20,Fig. 3, the

receive the carriers and being secured with the block 14 to the portion12 of the frame by .cap scr'ews 22. Each ofthe wiperlcarriers 24, 26,which receive stationary guide rolls 7 28 secured between the block 14and the cover plate ,16. Each carrier isconnected by a plate 16 beingrecessed to provide space to 18,20" is provided with two curvedcam-slots wiper carriers 18, 20 are secured respectively wipers 38, 38,each wiper having a beveled rear edge which engages a similarly beveledsurface on the wiper carrier and being held in position on the carrierby a stud 42. Forward movement of the plunger 34 causes bodily movementof the wiper carriers and wipers toward the shoe, and the rolls 28acting in the curved cam slots 24, 26 cause closing movement of thewipers relatively to eachother, the curvature of the cam slots 24, 26,being such that the wipers turn. about the meeting point of their edges.

To operate the plunger 34 a horizontal shaft 46 is mounted in theportion 12 of the frame and carries a sleeve 47 on which is an arm 48the upper end of which is bifurcated to receive a head 50 secured to theplunger 34 by-a nut 52 (Fig. 3), the head 50 having projecting pins 54carrying blocks 55 which engage slots 56 in the bifurcations of the arm48, the blockshaving flanges to prevent their slipping off the pins. Thesleeve 47 has a horizontal arm 58 to which is pivoted at 60 a rod 62.The lower end of the rod passes through the end of the rear arm 64 of alever fulcrumed at 66 to the frame 10. Between the arm 64 anda nut '68on the end of the rod 62 is a compression spring 70. Between the rod 62and the fulcrum 66 a rod 72 passes by the arm 64 and carries a block 74which is arranged to bear on the upper surface of the arm 64. The

rod 72 is connected at 76 to a treadle lever 78 fulcrumed at 80 to theframe 10 and held normally in elevated position by a spring 82.Depression of the forward end of the treadle lever 78 which has atreadle 84 turns the arm 64 and causes it to act through the spring 70to pull downwardly on tl e rod 62 which acts through the angle lever 58,48 to move the plunger 34 forwardly to advance and close the wipers.

Y In order to afford additional support for thewlpers, bracing members86, 88 are proan upper mounted thereon and a sole attached thereto, themargin of the sole extending beyond the last bottom, is supported on aplate20 (Fig. 2) which is secured by screws 92 to a segmental block'94(Fig. 4) seated in a member, 96 and so constructedand arranged that theblock 94 and the attached plate 90 can tip to a limited extent in themember 96 about an axis whichextends lengthwiseof'the last and islocated near ice , the last bottom. This-construction permits ment inthe frame 10 in a direction slightly rearwardly inclined from thevertical so that as the support is raised towardthehorn zontallyarranged wipers the support has a component of rearward movement whichtends to crowd the shoe lengthwise toward the wipers. in a horizontalplane with the shoe bottom downward enables the operator readily toobserve the action of the wipers on a shoe presented to the machine. Thelower end of the post 98 has a lost motion connection to an upper link102 of a toggle the upper oint of which is formed by a pin 104 extendingthrough the link 102 and ablock 106 which block is arranged for limitedsliding more 1 ment 111 a slot 108 formed 1n the post 98.

and is held'in place by a'strap 110 passing over the open end of theslot and secured by a bolt 112 to the post 98. The amount of lost motionwhich the block 106 has in the slot 108 is equal to or slightlygreaterfthan the amount of movement heightwise of the shoe which it isdesired to give the work support relatively to the wipers. Normally theend of the slot 108 in the post. 98 rests on the block 106.

The post 98 near its lower end has a transverse pin 114 to which isconnected the upper end of a rod 116 the lower end of which is arrangedfor free longitudinal movement in a connecting member 118 which ispivotedat 120 to a forward arm122 of the lever pivoted at 66 therearward'arm 64 of which has been referred to. On the rod 116 is acompression spring 124 which is held between the connecting member 118and a collar 126 adjustably fixed to the rod 116. Depression of theforward end of the treadle lever by the operators foot therefore actsnot only toadvance and close the wipers, as already described, but alsoacts to lift the forward arm 122 and hence, through the spring 124, toraise the =work support 90. The raising-of the work 7' V 70 may yieldand permit further upward movement of the support through the spring 124toeifect wiping of the upper heightwise of the toe toward the sole. Whenthe shoe support has been raised suh'ic'ientlyto cause the wipers topress the outturned flange of the upper against the projecting margin ofI the sole, the treadle is stilldepressible against The arrangement ofthe wipers both the springs 70 and 124 to trip the clutch in a manner tobe explained. V

.Thedescnbed movement of the work support can occur by reason of thelost motion of the slotted end of the post 98 relatively to theblock 106without causing movement of ..the-toggle link 102 the upper pivot ofwhich is in the block 106. The lower end of the link 102 ispivotedat-130 to an eccentric rod 132,

as .is also the upper end of the other link 134 7 of the toggle. Thelower end of the link 134 N is pivoted to a plunger 136 arranged formovement in alinement with the post 96 in a cylindrical bore in a member138 secured by -screws 140 to the frame 10. Movement ch9 the plunger islimited by a screw 142 the end" of whichengages a longitudinal slot inthe plunger 136. Beneath the plunger 136 and normally supporting it atthe upper limit of its movement is a light spring 144 surrounding whichis a heavy spring 146. Both springs rest on a plate 148 which can bemoved lengthwise of the springs by means of a screw 150 threaded throughthe bottom of the member138 and engaging the plate 148. The screw 150carries a gear 152 with which a pinion 154 on a rod'156 meshes, theupper end of the rod being provided with a crank handle 158. By turningthe crank the heavy spring 146, the upper end of which isrt shown asspaced from the lower end of the plunger 136, maybe raised bodily untilthe space between it and the plunger is taken up, 7

to vary the pressure exerted on the work by straightening of the toggle102, 134. Ad

.justment of the pressure can thus be made without tensioning the heavyspring.

The eccentric rod 132, described as connected to the center joint 130 ofthe toggle 102, 134, carries an eccentric strap which;;;

surrounds an eccentric 162 rotating on a shaft 164. A motor 166 isconnected through suitable reducing gears, as shown in Fig. l, to

a gear 168 on the shaft 164, and between the gear 168 and the eccentric162 is a half-revo-yl lution clutch mechanism, which may be of i anysuitable type, so that when the clutch is tripped the gear 168willimpart a half revolution to the eccentric 162 and cause it to stopwith the toggle 102, 134 straightened and the- 1 work under pressure.The clutch is thrown out by engagementof one of two stop projections170, 772 with the rear arm 174 of a stop lever pivoted at176 to theframe 10 and having a forward arm 17 8 carrying a stop screw p 180tolimit movement of the arm 174 toward a the clutch. The arm 178 carriesa slabbedoif pin 182 which engages an elongated notch 184 in therearface ofthe rod 72, described as connected to the treadle lever 78, thenotch;

-being of suflicient length to permit the desired movements .of' thework support and wipers by operation ofthe treadle as described withouttripping the clutch. However, when the toe of the shoe has beensatis-lidetails for controlling the eccentric and over-running of theclutch factorily lasted and is desired to have the work support operatedby power to force 'the projecting margin of the sole forcibly againstthe outturned flange of the upper, .which, of course, is backed up bythe toe-embracing wipers, the treadle can be further de zressed againstthe springs 70, 124unt11 the upper end of the notch 184 engages thei'pin 182 and raises'the arm 174 of the stop "10 lever away from thestop projection 170, permitting the clutch to operate and causerotationot the eccentric 162. Soon after the eccentric 162. starts, aface 186 on the eccentric-carry1ng member strikes the rod'72 and 15.

when the pressure is being released, herein shown by way of illustrationbut which form no part of the present invention, are fully j explainedin Letters Patent of the United States No. 1,674,085, granted June19,1928, on application of Ballard and Seely to which 're 'erence maybehad for more complete explanation thereof.

The block 1 upon which the wiper'carriers 18 0 are mounted, is providedon each a hole 190 to receive a heating unit- 192 the terminals of whichare indicated at 194. In treating some class-es of work, for

example those in which celastic material is included in the toe box, it15 desirable to have V the wipers heated to assist in setting andhardening the upper materials to hold them inlasted position.

In the shoe.

In that case the wipers "heat of the toebox and permit the gums exudedby the pressure on the flange ot' the upper to set and hold the flangeto the sole.

' The work to be operated upon consists, as t( r--receives it, of a lasta having secured to its bottom an extension sole 6 and an upper c whichis secured to the last atits rear end and includes lining between whichand the upper leather there is inserted a toe stiiiener or toe box, theupper, stit'tener and lining constituting the upper materials. In

For the sake ofconvenience and simplicity the upper in Fig. 2 of the drawings is shownas a single layer. It is a usual practice, just before the shoe ispresented to the lasting machine operator, to insert between the upperand lining a heated toe box of thcrmo-plaatic material, for example thewell-known. Beckwith toe box.

In the operation of the machine, the toe of a shoe having a heated toebox between its upper and lining placed on the support 90 and, bypressure of his foot on the treadle 9-}, the operator raises the shoesupport tl'irough the spring 12% which, however, is

Simultaneouslywith the upwarc movement of the work support the wipers 36, 38 areadvanced and closed yieldine'ly through the spring 7 0 which, when thewipers come into engagement with the shoe, permits the forward andclosing movement of the wipers to stop while the upward movement of theshoe continues to cause the wipers to wipe the upper heightwise of theshoe toe to *ard the last bottom. As this wiping operation progressesthe tension of the spring is progressively increased to force the wipersharder against the last with sufiicient pressure to enable them toperform the more difiicult, concluding portion of the lasting operationdurin which the upper materials are being shaped into the angle betweenthe last and the projecting margin of the sole. lncase a singledepression of the treadle is ineffective to produce the desired lastingeii-ect, the operator may release the treadle and repeat the operation.been satisfactorily lasted, the out-turned flange of the upper and theprojecting margin of the sole. will be held under pressure between thework support and the wipers. The operator then depresses the treadlestill farther against the springs 70, 12% to trip the clutch, whereuponthe eccentric 162 is given a semirotation to straighten the toggle 102,13st and applya' powerful upward thrust to the work support through thespring14l4, the machine stopping with the work under pressure. Thispower-r flected pressure insures that the outturned margin of the upperwill be flattened againstthe projecting margin'of the the thermo-plasticmaterial in ll be forced through the lining ion of the lining to thesole sole, and the t e box r to cause ,adl

as well'as to insurethat the upper, toe box and lining will-be securedto each other; The stopping of the machine with the work under Cirpressure permits time to be. allowed for the cooling and setting of theheated thermo-v plastic material as well as for the setting of the upperin lasted position.

In order that the operator may not have to wait for the setting to occurthe machine is preferably of duplex form, so that while the shoe remainsunder pressure in the mechanism on one side of the machine the mecha.nism on the other side may be operated to last and press another shoe.In case a still longer time is required for the setting of the uppermaterials, two duplex machines may be used by one operator. the lastingmechanisms being operated in succession. When it is desired to releasethe shoe, the treadle 84 is again depressed and the parts of the machineare restored to their normal position.
